Science
Mechanism of Action
This specialized ester blend serves as a primary constituent of L22, a patented lipid complex designed to emulate the natural surface lipid profile of young adult skin. Composed of essential fatty acids, triglycerides, and wax esters, it replenishes the skin's intrinsic lipid components. This action strengthens the protective skin barrier, effectively minimizing transepidermal water loss, boosting skin elasticity, and contributing to optimal, sustained hydration.
